mouse_update(3) Svgalib User Manual mouse_update(3)NAME
mouse_update - updates the mouse state
SYNOPSIS
#include <vgamouse.h>
int mouse_update(void);
DESCRIPTION
This reads in mouse events from the mouse buffer and updates the internal svgalib variables which store the current mouse position and but-
ton states. If there are no events to be read this routine returns immediately.
The function returns 0 if there was no event and a non-zero value otherwise.

This manual page was edited by Michael Weller <eowmob@exp-math.uni-essen.de>. The exact source of the referenced function as well as of the
original documentation is unknown.
It is very likely that both are at least to some extent are due to Harm Hanemaayer <H.Hanemaayer@inter.nl.net>.
Occasionally this might be wrong. I hereby asked to be excused by the original author and will happily accept any additions or corrections
to this first version of the svgalib manual.

mouse_init(3) Svgalib User Manual mouse_init(3)NAME
mouse_init, mouse_init_return_fd - specifically initialize a mouse
SYNOPSIS
#include <vgamouse.h>
int mouse_init(char *dev, int type, int samplerate);
int mouse_init_return_fd(char *dev, int type, int samplerate);
DESCRIPTION
These routines can be used to open the mouse manually, ignoring the mouse types or devices specified in the config file.
dev is the name of the mouse device (defaults to /dev_mouse).
samplerate may be one MOUSE_DEFAULTSAMPLERATE(150) or any other value. Probably it is in Hz.
type is one of the types which are listed already in vga_getmousetype(3).
If these routines are used it is not necessary to call vga_setmousesupport(3), but it's probably better to not use these and use vga_set-
mousesupport(3) instead.
The return_fd version returns the file descriptor of the mouse device to allow you to do further tricks with the mouse (but the filehandle
may change during a VC switch). The other version just returns 0 if successful. Both return -1 on error.
